Short answer: the Kali Audio IN-UNF for a specialized ultra-nearfield desk system, the Edifier R1280T for a conventional budget speaker. The IN-UNF uses a desk-mounted bass module with two opposed 4.5-inch woofers below 280Hz and time-aligned 4-inch/1-inch coincident satellites, but it is a very specialized system rather than a general desktop recommendation. The R1280T handled ASR’s demanding bass-heavy track without bottoming out, but its on-axis response is jagged.
What the Edifier R1280T offers: ASR’s Klippel-based measurements found the woofer handled a demanding bass-heavy track without bottoming out or audible distortion, and distortion stayed low and inaudible at a normal 86dB SPL listening level. Watch for: On-axis response is jagged rather than neutral, with a woofer resonance around 5kHz and a tweeter peak near 10kHz that also show up in the directivity data.
Buy the Edifier R1280T if the price is the priority over sound quality, or the Kali Audio IN-UNF if sound quality is the priority over the price.

Edifier R1280T: $149.99 per pair Amazon eBay
Pros: ASR’s review found useful moderate-level bass output from an inexpensive powered pair. Remote volume and bass/treble controls make it easy to use without separate amplification. Measured bass reaches -3dB around 63Hz. Measured bass extension of 63Hz (-3dB).
Cons: Preference scores of 2.41 standalone and 5.02 with an ideal subwoofer reflect substantial tonal limitations, not just missing bass. The response spans 5.5dB from 300Hz to 5kHz, and listening-window narrow-band deviation is 0.650. Resonances and treble unevenness affect reflected sound too. Listening height is important, and high-level compression changes the balance.

Kali Audio IN-UNF: $699 per pair Kali Audio eBay
Pros: A specialized ultra-nearfield system with coaxial satellites and an opposed-woofer bass module designed to sit on the desk. Erin found it worked much better when positioned using Kali’s placement template, with useful agreement between the intended response and close-range moving-microphone measurements. DSP placement controls and varied inputs make it a thoughtful solution for the right desk.
Cons: The intended desk geometry is part of the acoustic design. The bass module and prescribed spacing occupy considerable desk space and may conflict with large monitors. It is not designed for arbitrary room placement.
